In matplotlib axes is not the plural of axis. It has its own meaning specific to the API. And at the same time it's the plural form of another word (axis) which is also relevant in this context and it sounds almost identical when pronounced.
I like the wording in the MATLAB docs (since Matlab committed the original sin, the axes/axis/figure API has been around since the late '80s, matplotlib is just a port to python):
